Hi Jon,
I'm definitely interested in at least the mini-contacts package since I'm trying to put together a prototype and need to manage some contact information. I did not want to answer for OpenACS since I am not associated with the OpenACS project and have no way to add it to their public repository even if I work with Maurizio to bring it up to date.
I will however, gladly use it as a starting point if you can send it or upload to a shared location somewhere. Thank you.
